Honeywell HCD 6003, HCD 6010, HCD 6050, HCD 6150 DATASHEET

The switching differential is not adjustable. The low switching differentials are for the lower setting
range; the higher values relate to the upper ranges.

Pressure switches of the HCD series are suitable
for neutral and non-aggressive gases. They can
be used for monitoring overpressure and differ­ential pressure. For overpressure detection the
pressure side is connected to the lower connec­tion piece G 1/4”; for vacuum detection the
pressure side is connected to the upper

connection piece G 1/8” (remove sealing cham­ber). For differential pressure detection the high
pressure is applied to the lower connection
piece (G 1/4”) and the low pressure side to the
upper connection piece (G 1/8”). A pressure
measurement connector (9 mm ø) is available for
accurate setpoint adjustment.

Mounting position

Horizontal with connection pieces pointing
downwards.

Type of protection IP 40 according to DIN

40050.

Mounting

Either directly on pipe or with mounting brack­et (supplied) on a vertical surface.

Setting the switching point

Remove the cover and turn the setting spindle
marked +/– in the corresponding direction.
The scale shows only guideline values. For
accurate setpoint adjustment it is necessary to
use a pressure gauge which can be attached
to the measuring point (9 mm ø pressure
measurement connector).

Switching function Single pole switching.
